Your Walkthroughs and Techniques
Post descriptive walkthroughs of watches you have stripped down and serviced and/or repaired, parts you have made or techniques you wish to share.
This is an interesting section where we post our challenges and how we have over-come them. You can also post walkthroughs and share your techniques.
SECTION RULES
This section is strictly for those posting real step-by-step walkthroughs of actual repair or servicing techniques relating to watch repair and/or horology in general. The idea is that we help each other by describing or sharing our repair techniques, or telling a story of how we have progressed.
If you are not posting step-by-step walkthroughs, such as - you would just like to showcase a completed repair job, then please choose a more appropriate sub-forum for your content. If your post is not deemed to be a legitimate walkthrough then a moderator will move your post to the appropriate section without notice. Thank you for your co-operation.

Not so fast- (didn't realize how many makers made this shape)- it actually appears to be a Nouvelle Fabrique (Tavannes) S.A. -
Thank you @nickelsilver ! Definitely close! The differences may just be superficial/decorative (differences in train bridge and balance cock shape). For me, the question is if I'd find the exact spare part for the exact movement (balance staff, ideally with spring or even entire cock). Or if I should just find another movement entirely that fits into the watch. The Lorsa 514 would then fit well (by it's external dimensions) and it's dirt-cheap on eBay. -
Cool, good luck with your 620!! Yes, 20x the price is the correct calculation drop-for-drop. Then again, I probably won't even finish my 5ml of 9504 before it's expiry date (plus 1-2 years). And with the DX, I'd probably end up throwing away 90% of the tube by the time it expires. I did also start with 2-3 pocket watches, then 2 men's watches (last one, a Vostok 2414, with a good final result; amplitude around 300°)... and now already the 625 (for a friend!) 😬. I'm very nervous about it, but also very excited, thrilled. And well, worst case, I can get a whole replacement movement for around 80 USD off eBay.

I calc it as nearly 20x more expensive, so worth remembering when you've used the 9504 😀 I'm oiling a 620 now, in between typing. One problem with smaller (ladies) watches, is that due to the smaller part sizes, the frictional forces are relatively larger - especially on the smaller balance due to it's much lower inertia. Therefore parts have to be really clean and free from dust and dirt to get good performance. As a beginner I started on pocket watches, because they are larger and easier to start on, and that big balance is a lot easier to get swinging nicely. -

Looks a lot like an FEF 150 (Fleurier). Or a Buren 35 Actually it must be Buren, the movement side is pretty dead-on, but maybe a slightly different caliber? Ranfft doesn't have much for them in the form movements.
